The vivo X300 Ultra and POCO F9 Ultra share the same listed chipset, Qualcomm’s Snapdragon 8 Elite Gen 5, so the choice comes down to what each phone is built to emphasise. vivo puts its effort into cameras, with a ZEISS-branded three-camera system and optional telephoto extenders. POCO leads with display refresh rate, a larger rated battery and gaming claims. On price, no like-for-like comparison is currently available: vivo publishes suggested prices in China, while the POCO official pages checked in early October 2026 give no matching price, so a reliable price difference cannot yet be stated.
What the two phones share
Both models list the Snapdragon 8 Elite Gen 5 platform, built on a 3nm process. vivo’s China specification page gives the CPU as two cores at 4.6GHz and six at 3.62GHz (vivo China X300 Ultra specifications). POCO’s specification page pairs the same chipset with a VisionBoost D8 dedicated graphics chipset (POCO F9 Ultra specifications).

A shared chipset name does not mean identical sustained performance. Phone makers tune cooling, power limits and thermal behaviour differently, and neither company’s pages report a sustained-load test that would let you compare the two directly. POCO’s gaming performance figures are labelled as its own internal test data, and the company notes that results vary by title and settings (POCO F9 Ultra product page).

Cameras: different design priorities
The clearest difference is how each company builds its camera system. vivo uses three 200MP-class or 50MP lenses at 14mm, 35mm and 85mm equivalents, which gives the phone a wide, standard and tele set on paper, with a separate telephoto extender for longer reach. POCO uses a 200MP main camera with a periscope telephoto at 120mm equivalent and a 17mm-equivalent ultra-wide.
The two designs reach telephoto differently. vivo’s system relies on a fixed 85mm lens on the phone and, for longer focal lengths, on optional extenders. POCO’s periscope lens gives a longer built-in reach without an accessory. Which approach produces better photographs depends on sensor processing, colour tuning and real shooting conditions, and none of the official pages establish that comparison. Treat the focal lengths as a description of how each camera system works, not as evidence of image quality.
The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Video is also described differently. vivo highlights multi-focal 4K at 120fps with 10-bit Log and Dolby Vision support. POCO’s specification lists 8K at 30fps and 4K up to 60fps for rear video. Frame-rate and format claims are only as useful as the shooting mode you actually use, so check whether a feature is available on the lens you plan to use.

Display and gaming
POCO’s headline display figure is the refresh rate, up to 185Hz on a 6.9-inch AMOLED panel at 2608 × 1200. The 185Hz figure is a maximum. The company states that refresh behaviour varies by interface and game, so it will not hold across every app. POCO’s gaming claims are limited to selected titles and test conditions it describes as internal.
vivo’s official pages checked for this article do not state an X300 Ultra display specification, so a display comparison cannot be made from the sources available. Check vivo’s current official specification for your region before comparing screens.
Battery and charging
On the rated figures, POCO has the larger battery, at 8050mAh typical against vivo’s 6600mAh typical. vivo’s China page also lists a 6395mAh rated value, so the two companies report battery capacity differently. Wired charging is the same at 100W. POCO’s wireless charging is listed at 50W, compared with 40W for vivo.
These are rated values. They do not show how long either phone lasts. POCO’s two-day battery claim comes from its own simulated test and the company acknowledges that usage varies. Neither company has published an independent endurance result in the sources reviewed here, so compare capacity and charging speed as specifications, not as battery life.

Build and water resistance
The phones are close in size and weight. POCO is slightly thicker at 8.74mm and 235g. vivo’s thickness depends on colour, at 8.19mm or 8.49mm, and its weight at 232g or 237g.
POCO rates the F9 Ultra IP68 under laboratory conditions it specifies. That rating does not mean the phone can be used freely in water. POCO’s footnote advises against using it at the beach or in a pool. vivo’s pages checked here do not state a water resistance rating, so do not assume the two phones are equally protected.

A verified price difference between these phones cannot be stated yet. vivo’s China page publishes suggested prices by configuration, but POCO’s official pages checked here give no price, and the TechRadar review of the POCO F9 Ultra (published 15 September 2026, TechRadar review) displays conflicting UK price figures, so its numbers should not be quoted without confirmation.

| vivo X300 Ultra configuration (China) | Suggested price |
|---|---|
| 12GB RAM + 256GB storage | CNY 6,999 |
| 12GB RAM + 512GB storage | CNY 7,499 |
| 16GB RAM + 512GB storage | CNY 7,999 |
| 16GB RAM + 1TB storage, satellite edition | CNY 8,999 |
| 16GB RAM + 1TB storage, photographer kit | CNY 11,999 |
These are China suggested prices, not street prices. The photographer kit is priced substantially higher than the base 16GB and 1TB model, but the page does not confirm which accessories it includes, so do not assume it contains the telephoto extenders.
To build a fair price comparison, match these details for both phones before comparing:
- Country and official or authorised seller.
- Exact RAM and storage configuration.
- Currency, tax treatment and any promotions active on the same date.
- Included accessories, including whether a camera extender or charger is in the box.
- The date the price was checked, since prices change.
Checking current availability
Because local prices and bundles change, check the official storefront for each phone in your market and record the figures with the date. vivo’s China specification page is the best starting point for configuration details in China, and vivo’s global product page covers the feature set for other markets. POCO’s global specification page is the reference for POCO’s listed hardware and test footnotes.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsThe Bottom Line
Choose the vivo X300 Ultra if camera system design matters most to you, particularly if you want the option of ZEISS-branded telephoto extenders for longer reach. Choose the POCO F9 Ultra if you prioritise the high-refresh display, the larger rated battery, the faster wireless charging and a built-in periscope telephoto. Both run the same Snapdragon 8 Elite Gen 5 chipset, so neither wins on the processor alone. Do not decide on price until you have checked the same storage configuration, currency and included accessories in your own market.
